Air Operated Pinch Valves for all Applications

air operated pinch valves

The solution for isolating and regulating/metering abrasive, corrosive and fibrous products with a free flow such as granulates, powder, pellets, dust and liquids containing solids, etc. See our application area for more.

Product Overview

Air Operated Pinch Valves

See how the AKO Air Operated Pinch Valves work:

Air operated pinch valves are operated by supplying compressed air or fluid into the housing, which compresses the rubber sleeve/liner. The special manufacturing process of the sleeves ensures high rebound elasticity. The rubber sleeve closes in the same way every time due to the elliptical design of the body, forming a lip shape to ensure a completely tight shutoff of the product flowing through (even with large solids). This guarantees the longest service life of the rubber sleeve/liner, and results in energy savings.

The maximum operating pressure for all AKO air operated pinch valves is dependent on the nominal diameter and is around 2-6 bar. As soon as the supply of compressed air or fluid is interrupted and the valve casing is vented or drained, the durable rubber sleeve is opened by its rebound elasticity/resilience, enabling the pressure in the medium to flow through the full passage of the air operated Pinch Valves.
